Description of key information
Hydrolysis expected at pH <7, with rapid hydrolysis (ca. 2 minutes) expected at pH <2.
Key value for chemical safety assessment
Additional information
n-Vinylpyrrolidone (nVP) is considered readily biodegradable and with hyrolysis expected only under acidic conditions. At pH 1.2, a half-life of approximately 1.5 minutes has been reported and, at a pH of 7.2 the substance was found to be stable for at least 24 hours (Hawi, et. al., 1987). As part of a study in which nVP was administered in drinking water, it was reported to be stable in water for at least 4 days (BASF, 1986).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
